- `androidx.awesome.lib` is also a valid alias
- but `this.#is.not!`

Then type safe accessors are generated for _each subgroup_.
For example, given the following aliases in a version catalog named `libs`:

`guava`, `groovy-core`, `groovy-xml`, `groovy-json`, `androidx.awesome.lib`

We would generate the following type-safe accessors:

- `libs.guava`
- `libs.groovy.core`
- `libs.groovy.xml`
- `libs.groovy.json`
